MSI Upgrade Table

The Upgrade table contains information that’s used when an Installer database is used to make a major upgrade to an existing product. This table contains following columns:

UpgradeCode:

The UpgradeCode property in this column specifies the upgrade code of all products that are to be detected by the FindRelatedProducts action. Unlike the ProductCode, different products may share the same UpgradeCode.

VersionMin:

This column specifies the minimum version to be upgraded. Lower boundary of the range of product versions detected by FindRelatedProducts. A null value means there is no lower bound on the version to be upgraded.

VersionMax:

This column specifies the maximum version to be upgraded. Upper boundary of the range of product versions detected by the FindRelatedProducts action. A null value means there is no upper bound on the version to be upgraded.

Language:

This column contains the set of languages detected by FindRelatedProducts that are to be upgraded and are separated by semicolons. A null value means that any language can be upgraded.

Attributes:

This column can contain any combination of the bit flags as shown in below tables:

Bit flag ( decimal)	Attribute
1	To enable the MigrateFeatureStates action
2	To detect but not change previous versions
4	To install the new version even if the old version can’t be removed
256	To include VersionMin in the versions upgraded
512	To include VersionMax in the version to be upgraded
1024	To upgrade all languages except those listed in the Language column

Remove:

This column contains a comma-delimited set of names of existing features to be removed.

ActionProperty:

When the FindRelatedProducts action detects a related product installed on the system, it appends the product code to the property specified in this field. The property specified in this column must be a public property and the package author must add the property to the SecureCustomProperties property. Each row in the Upgrade table must have a unique ActionProperty value. After FindRelatedProducts, the value of this property is a list product codes, separated by semicolons (;), detected on the system.
